The New Triangle of Egypt, Israel, and Hamas

Over the past year, Israel and Egypt have used a little-known, legally permissible understanding -- the Agreed Activities Mechanism -- to bypass restrictions on the number and type of Egyptian forces permitted in much of the Sinai. In doing so, they have made de facto modifications to their 1979 peace treaty without resorting to the diplomatically risky procedure of "reviewing" the treaty itself. As a result, considerable Egyptian army forces are now constantly deployed in central and eastern Sinai (Areas B and C of the peninsula, respectively), in a manner and scope never envisaged by the teams that negotiated the treaty more than three decades ago. Going forward, this new reality on the ground is unlikely to be reversed and is bound to have profound consequences for Egyptian-Israeli security cooperation, Cairo's ongoing counterterrorism campaign, and the fate of Hamas in the neighboring Gaza Strip.
